**distance from centre of enlargement to point on object**

I read this to say that the lengths of the sides are reduced by a scale factor of 1/3. One of the sides has length 6.3 cm and one third of 6.3 is $\frac13 \times 6.3 = 2.1$ cm. Thus the length of the new rectangle is 6.3 - 2.1 - 4.2 cm.... Now calculate what the weight and cross-sectional area of the lower leg bone of a man who is an enlargement by a scale factor of two of the original man. Get the students to show why humans cannot grow larger and larger and that at some point the enlarged human bones would no longer be strong enough to carry the weight of the enlarged body.

Similarity and Congruence . Two objects are similar if they have the same shape, so that one is an enlargement of the other. Two objects are congruent if they are the same shape and size. Scale Models and Factors. In an enlargement or reduction. Corresponding angles are equal... shapes are similar because there is a common scale factor for all of the sides.The sides of the larger ﬁgure are twice as long as those of the smaller ﬁgure.What do you say to the student to explain why

A scale can be written as the ratio of two lengths, or as the ratio of two numbers. For example: scale = 1 cm : 5 m or scale = 1 : 500 Matching angles are equal, and the ratio of matching lengths equals the scale. how to get over a girl you see everyday Similarly, dividing the larger triangle's side lengths by the scale factor will give you the side lengths of the smaller triangle. Set up ratios of the corresponding sides of the triangles. For example, the ratio of small to big triangle sides in two triangles is 5/10, 10/20 and 20/40.

When you resize a shape it gets bigger or smaller. but it still looks similar: all angles stay the same ; relative sizes are the same (for example the face and body are still in proportion) Note: here we call it resizing, but other people call it how to find the independent variable in an article Answer. scale factor = a dimension of the larger shape / the same dimension of the smaller shape

## How To Find The Scale Factor Of Two Shapes

With a negative scale factor the number part of it tells us if the shape is to be made bigger or smaller, while the negative sign tells us that the image and object are on …

- Similarity and Congruence . Two objects are similar if they have the same shape, so that one is an enlargement of the other. Two objects are congruent if they are the same shape and size. Scale Models and Factors. In an enlargement or reduction. Corresponding angles are equal
- In this case we would say that the linear scale factor is 3. The linear scale factor for The linear scale factor for similar objects can be evaluated using the ratio of the corresponding side lengths.
- If you find it a little bit of a big leap to go from just an arbitrary rectangle transformation to maybe these more generalized shapes, you can imagine-- so T is going from there to there. It's always nice to draw that arrow. But if you view it as a bit of a leap to make that jump from rectangles to curves, you can imagine this shape to be able to be constructed by a bunch of arbitrary
- The scale factor of figure B to A is: 1/3 9 * 1/3 = 3; 15 * 1/3 = 5 How does the scale factor going from the large figure to the small figure compare to the scale factor of the small figure to the large figure?
